In a surprise move, Caltex Socceroo legend Harry Kewell has parted ways with English Premier League club Waftford FC as their U-21s coach.

'Unfortunately results haven't been on my side,' he wrote on his Twitter feed.

'However, I'm extremely proud that 3 of my players have made their debut for the first team and 5 others have been in the squad."

He thanked Watford and said he was looking forward to his next challenge.

Kewell joined the Hornets in mid-2015 after his playing career finished to oversee Watford’s next generation as they embarked on their first season in the Under-21 Professional Development League 2 South.
